Mogwase - Former North West provincial deputy police commissioner Major General William Mpembe and eight other policemen appeared briefly in the North West High Court on Monday.
The case was postponed to September 14 for a pre-trial conference. The pre-trial could not proceed on Monday, as the defence still required time to consult.
The accused are facing charges relating to a shooting incident in Marikana near Rustenburg in August 2012.
Mpembe, now head of security at a mining house in Marikana, is accused of the murder of Semi Jokanisi, Tembelakhe Mati, Warrant Officer Hendrik Tsietsi Monene, and Warrant Officer Sello Ronnie Lepaauku.
He is charged alongside retired Colonel Salmon Johannes Vermaak, 53, who together with Constable Nkosana Mguye, 38, Warrant Officer Masilo Mogale, 49, Warrant Officer Katlego Joseph Sekgweleya, 39, and Khazamola Phillip Makhubela, 49, are accused of the murder of Pumzile Sokhanyile.
